Journal ArticleDOI
Top-down estimate of China's black carbon emissions using surface observations: Sensitivity to observation representativeness and transport model error
Xuan Wang,Xuan Wang,Yuxuan Wang,Jiming Hao,Yutaka Kondo,M. Irwin,J. William Munger,Yongjing Zhao +7 more
TL;DR: In this article, the authors examined the sensitivity of top-down quantification of Chinese black carbon emissions to the temporal resolution of surface observations and to the transport model error associated with the grid resolution and wet deposition.
Mixing States of Light-absorbing Particles Measured Using a Transmission Electron Microscope and a Single-particle Soot Photometer in Tokyo, Japan
TL;DR: In this article, the authors examined the changes in the mixing states and abundance of strongly light-absorbing carbonaceous particles by using transmission electron microscopy (TEM) and single-particle soot photometer (SP2), as well as of iron-oxide particles, in Tokyo, Japan.
Journal ArticleDOI
Significant alteration in the hygroscopic properties of urban aerosol particles by the secondary formation of organics
Michihiro Mochida,Michihiro Mochida,Takuma Miyakawa,Nobuyuki Takegawa,Y. Morino,Y. Morino,Kimitaka Kawamura,Yutaka Kondo +7 more
TL;DR: In this paper, the temporal variation in the hygroscopicity of urban aerosol particles was investigated in Tokyo based on the hythroscopic growth factor (g) measurement in the summer of 2004.
Journal ArticleDOI
Measurement of nitric oxide from 7 to 32 km and its diurnal variation in the stratosphere
TL;DR: A chemiluminescent balloon-borne sonde, designed to measure nitric oxide with a high degree of precision, has been developed in this paper, and the first ascent and descent profiles, obtained with solar zenith angles of less than 57° coincided even in detail to within 5% between 22 and 32 km.
Journal ArticleDOI
Effects of biomass burning, lightning, and convection on O3, CO, and NOy over the tropical Pacific and Australia in August–October 1998 and 1999

TL;DR: In situ measurements of O3, CO, NO, total reactive nitrogen (NOy), NO, and non-methane hydrocarbons (NMHCs) were made over the western Pacific Ocean and Australia during the Biomass Burning and Lightning Experiment (BIBLE) A and B conducted in August-October 1998 and 1999 as mentioned in this paper.
